CAR-SPRING SUPPORT.

SPEGIFICATIN forming part of Letters Patent No. 288,779, dated November 20, 1883.

Application filed September 1, 1883. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM Don, a citizen ofthe United States, residing at New York, v in the county and State of New York, have invented new and useful Improvements in Car- Spring Supports, of which the following is a speciiication. l

My invention relates to the construction of supports for the springs of railroad-cars, and especially street-cars.

In the accompanying drawings, Figure l shows a car-springsupport, partly in. side view and partly in section, embodying my invention. Fig. 2 is a horizontal section on the line fc as, Fig. l.

Similar letters indicate corresponding parts.

The letter A designates one of the sills of a street-railroad car, and Ba sill-plate attached tothesill by screws or other suitable fastenings.

G C indicate girders or cross-timbers under the sill, and D a suspension bracket or stirrup having its opposite ends provided with att-aching-plate E, whereby it is secured to the lower sides of the girders. rlhis suspension-bracket D is made in sections, which in this example are three in number, they being marked D Dl D, respectively,4 and which are connected together, preferably near the ends, by screw-couplings F, having right and left hand screw-threads to engage the ends of adjacent sections, so that by properly adjusting these couplings the bracket can be tightened to compensate for any loss in the tension of the springs presently described.

Heretofore the suspension-bracket D has been made in one piece extending up through the girders C G, and having screw-nuts bearing on the girders for its adjustment. This arrangement, however, permits the bracket to work up and down in the girders in case of any loss in the tension of the spring, causingv pension-bracket D 'are located carsprings G G, of spiral form, through each of which springs extends abolt, H, having one end connected to the sill-plate B and the other end to the bracket. Each of the springs G G is inclosed in a casing, I, which is divided transversely into two parts or sections, I I, which are fitted into each other, and are closed at the ends, where one abuts against the sill-plate B and the other against a plate, J, projecting laterally from 6o the car-axle box K and working on the bolts. The lower section, I2, of the casing is movable, and thus allows the car-springs to yield to the downward pressure of the car-body upon the axle-box in the usual manner. The laterally- 6 5 .projecting plates ,I are common to axle-boxes when used in connection with springs which are arranged in the positions shown.

Between the springs G G and the closed ends of the spring-casings I are interposed wash- 7o ers L, of ordinary form. The upper section,

I', of each spring-casing is iii/red to the sill-plate B by the proper bolt H, which to this end is provided with an inverted conical shoulder,

N, engaging a corresponding socket in the end of the section named, the bolt thence extending up through the sill-plate, and having a nut, O, on its upper end bearing o'n the sillplate for tightening it. The lower end of each spring-bolt H is connected to the bracket D 8o by clamping-nuts P l?one'above and the other below the bracket; and on the upper nut rests a washer, Q, of india-rubber or other similar material, forming a cushion for the lower or movable section, I?, of the springcasings.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, substantially as hereinbefore set forth, with the ear sill and gird- 9o ers, of the sectional suspension-bracket secured to the girdersfand the screw-couplings uniting the sections of the bracket.

2. The combination of the car-sill A, the transverse girders C, the spring-supporting 9 5 suspension-bracket D, composed of sections having screw-threaded ends, and plates attached to the transverse girders, and screwthreaded couplings adj ustably connecting the threaded ends ofthe seclions,for adjusting the roo suspension-bracket to compensate for loss in Y the tension of the springs, substantially as described.

8. The combination, substantially as here inbefore set forth, With the suspension-bracket, of the spring-bolts having one end connected to the bracket, the axle-box having laterally-projecting plates to engage the bolts, the spiral springs, and the sectional spring-caslngs.

4. The combination, substantially as hereinbefore set forth, with the suspension-bracket and sill-plate, of the sectional spring-casings and the bolts, each having the inverted conical shoulder tted into a socket in the end of the upper section of the spring-casings, and having a nut on the upper end bearing on the sill-plate.

5. The combination ofthe suspension-bracket, the springs G, the bolts H, passing'through the springs and the bracket, the nuts I P', secured to the bolt on opposite sides of and against the bracket, to rigidly connect the lower ends of the bolts With the brackets, the elastic Washers resting upon the upper nuts, P, and the axle-box having arms J resting on the Washers, 'substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing Witnesses.
